Inspired by the mad max ripsaw from fury road, I've been working on a muscle car with tracks. I haven't built anything with tracks for years, so I'm aiming for robustness and fun rather than realism and complexity. For that reason, I have no suspension on the tracks, just a tension system which can also adjust the stance of the vehicle, operated by linear actuators.

Originally I was going to have suspension, but I found the tracks were coming off when not even driving.. I don't fully expect to finish this, but it's been fun to just play around with a silly concept so far. I'm thinking about a 2 speed gearbox, I want to try use the planetary hub in a gearbox with dual clutch rings so the hub doesn't cause extra resistance when not in use, not sure yet though...

Also, I made a studio file for the bodywork if anyone wants it:

Thanks for reading- I'm feeling a bit shakey about this build so some ideas/encouragement would be appreciated...

Looks very good! :thumbup:

For making it sturdier, maybe you can try to move the track inwards or/ and make them shorter, in order to place them under the body.

I've been away from this for a little while, but here's an update on why. The left track always runs slower than the right track so it doesn't drive in a straight line. I checked everything moves freely and swapped the tracks around, but I think the problem is the planetary hubs or the buwizz motors.

Has anyone got any ideas what to do? I'm thinking xl motors instead of buwizz ones...

That is unfortunate, I don't know what the culprit might be, have you got any other motors laying around?

No actually, all my other motors are tied up in two suspiciously identical trophy trucks...

I've made some progress on my... whatever this thing is. 

I solved the issue of the buwizz motors having different speeds by using good old PF XL motors instead. The power from the XL motors goes into knob gears, then to the tracks. But between the motors is a differential, for driving the fake engine. I made a colorful recreation of it, since the actual one is obscured under panels and built in all black. Notice the bracing on the sides of the 5x7 frames connecting into the bodywork, which is acting as a structural element.

Then, since this vehicle is already a bit stupid, I added a rear winch!

Additionally, the entire underside of this vehicle is paneled up, meaning it could be good for offroading... if it didn't use tracks... oh well!

Anyway, I'm just having a bit of fun building something wacky now. Next up: power for the front winch, fake engine install, working steering wheel?
